In SharePoint JSOM, following is the correct way to set the lookup column in list:

var lkfieldsomthing = new SP.FieldLookupValue();  
current.set_item('InternalNameOfLookupField', lkfieldsomthing);


  1. Lookup_ID : The unique, SharePoint default ID of the list item from where your are referencing your lookup(Source/Provider List).

  2. InternalNameOfLookupField : Internal name of lookup field in your Destination/Consumer list.

  • I'm going to add the input value in a lookup column ?? var Name = $("#txt").val(); – Alice Feb 11 '19 at 14:55
  • Free text will not get added in the lookup field. To set the lookup field you need to save the ID of the list item from where your are referencing your lookup(Source/Provider List). – Ganesh Sanap Feb 11 '19 at 14:58
  • Are you using custom html form? – Ganesh Sanap Feb 11 '19 at 15:00
  • I used the following html tag : <input title=" Client" id="Clients" style="border:none" /> – Alice Feb 11 '19 at 15:04
  • You cannot use the free text for lookup columns. You need to use the select tag and bind the list items IDs as a value to each option in your select tag. – Ganesh Sanap Feb 11 '19 at 15:17
